Esri EGMP2201 Exam Dumps - Actual Questions Answers

In a branch versioning workflow where thedefault versionis the published version that users see and editors can post edits to, setting the access level toProtectedis the best choice.

1. What Does the Protected Access Level Do?

TheProtectedaccess level allows users to view and query the version but restricts editing to authorized users only.

This ensures that only authorized editors can post changes to the default version, maintaining data integrity while allowing portal users to access the published version.

2. Why Not Other Options?

Public:

A public version allows anyone with appropriate permissions to edit the version. This could lead to uncontrolled changes and data integrity issues.

Private:

A private version restricts access to the version to only the owner and specific users, which is unsuitable when the default version is meant to be the published version visible to all portal users.

Steps to Configure Protected Access Level:

OpenArcGIS ProorArcGIS Enterprise Manager.

Navigate to the version management settings for the default version.

Set theAccess LeveltoProtected.

Ensure that editors with appropriate privileges are assigned to post changes to the default version.

Conclusion:

Setting the default version toProtectedensures a balance between providing access to portal users and restricting edits to authorized personnel.

Scenario Overview:

The organization hasArcGIS Enterpriseand requires versioned editing.

The project mandates tracking which user deleted a feature from thedefault version.

Why Branch Versioned Editing?

Branch versioningsupports versioned editing workflows and integrates seamlessly witheditor tracking, including operations like tracking who deleted a feature.

It is ideal for web-based workflows inArcGIS Enterpriseand allows for direct interaction with feature services.

The default version remains accessible for analysis while enabling the organization to track user edits, including feature deletions.(ArcGIS Documentation: Branch Versioning)

Alternative Options:

Option B: Traditional versioned editingsupports versioned workflows but does not inherently track who deletes features unless additional workflows are implemented (e.g., custom fields or triggers).

Option C: Nonversioned editingdoes not support versioning workflows or user tracking.

Thus,branch versioned editingis the best workflow to support versioned editing while tracking deleted features.

Amosaic datasetis the most appropriate storage mechanism for visualizing and managing a centralized folder of imagery, especially when the imagery is to be accessed across an organization through an enterprise geodatabase.

1. What is a Mosaic Dataset?

A mosaic dataset is a geodatabase structure optimized for managing and serving large collections of raster data, such as satellite imagery or aerial photographs.

It provides dynamic mosaicking, rendering, and query capabilities.

2. Why Use a Mosaic Dataset?

Centralized Management: A mosaic dataset can reference multiple images stored in a folder without duplicating the data, maintaining a centralized source of imagery.

Scalability: It supports large collections of raster data and allows for efficient querying, rendering, and analysis.

On-the-Fly Processing: Provides options to apply image processing and rendering rules without modifying the source data.

Enterprise Access: Mosaic datasets stored in an enterprise geodatabase can be published as image services for access across the organization.

3. Why Not Other Options?

Raster Dataset:

This option is for storing a single image or raster layer in the geodatabase, not suitable for managing multiple images.

Raster Catalog:

Raster catalogs organize rasters but lack dynamic mosaicking, rendering, and query optimization capabilities. They are less efficient and are now considered outdated in favor of mosaic datasets.

Steps to Create and Use a Mosaic Dataset:

OpenArcGIS Proand connect to the enterprise geodatabase.

Create a new mosaic dataset using theCreate Mosaic Datasettool.

Add rasters to the mosaic dataset using theAdd Rasters to Mosaic Datasettool, pointing to the centralized folder of imagery.

Publish the mosaic dataset as an image service in ArcGIS Enterprise for organization-wide access.

Conclusion:

Amosaic datasetprovides the best functionality for managing, visualizing, and sharing multiple images from a centralized folder within an enterprise geodatabase.
